SPECIFICATION forming part of Letters Patent No. 513,916, dated January 30, 1894.

Applicationiiled August 12, 1892. `Serial No. 442,858. (No model.)

To all whom t may concern:

Be it known that I, ELI H. GosLIN, a citizen of the United States, residing at Washington, 1n the county of Daviess and State of Indiana,haveinventedanewanduseful'Wrench, of which the following is 'a specification.

My invention relates to an improvement in Wrenches, of the class known as pipe-wrenches, the object of the improvement being to provide a simple, cheap and effective device, comprising a minimum number of parts, united 1n a simple and strong manner.

.A further object of my invention is to provide a construction of the jaws whereby the movable or swinging feature of the sliding Jaw may be avoided. Further objects of my invention will appear 1n the following description the novel features thereof being particularly pointed out v1n the appended claim.

In the drawings, Figure l is aside view of a wrench embodyingmy improvements. Fig. 2 1s a face view of the fixed jaw. Fig. 3 is a transverse section through the pivoted link.

A designates the shank of my improved wrench, having at its lower end a handle, B, and C designates the fixed upper jaw, which is attached to the shank. The shank is rectangularin cross-section, and is provided near its lower end with a series of teeth or transverse notches, as shown at D.

E represents the sliding jaw, secured rigidly to a. stem, F, having a dat rear side or edge to bear firmly against the edge of the shank.

Pivotally connected to the stem of the sliding jaw, near its lower extremity, is a guiding link, G, which is yin the form of a loop, the closed end of which embraces and bears against the outer side of the lower end of the stem of the sliding jaw, and the parallel arms of which pass upon opposite sides ofthe shank and extend beyond the rear side of the saine.

Between the free ends of the side arms of the loop-shaped guiding'link, G, upon atransverse pivot pin, H, is fulcru med the cam-lever, K, the head of which is adapted to bear against the rearside of theshank.

The stem of the sliding jaw is provided at its lower end with a rearwardly projecting detent, L, which extends slightly in rear of the plane of the rear side of the stem to en-` gage the serrations or notches in the front side of the shank, as shown in Fig. l, and by pressing the free end of the handle of the cam lever toward the shank the said detent is caused to engage said notches and hold the sliding jawstationary. An upperpivotal guiding-link, M, is connected to the upper end of the stem of the sliding jaw; this link is loopshaped, also, the free ends of its parallel arms being pivotally connected to the sliding jaw, anditsfclosed end passing around and bearing against the three sides of the shank. The face of the fixed or upper jaw is concaved, as shown, and is provided with diagonal serrations orridges, N, and the face of the sliding jaw is downwardly-inclined, or diverges from the face of the fixed jaw, toward its front end, and is convexed, as shown. The combination With a concaved and'diagonally serrated upper jaw of a divergent and convexed lower jaw, the'latter having a smooth face, enables a pipe or rod to be firmly gripped without the swinging feature which is common to pipewrenches. By doing away with this swinging feature l work asimplification of the construction of pipe and' rod Wrenches, without detracting from the effectiveness of the tool. I also provide an implement which may be more cheaply manufactured and which is less liable tobe put out of order by use, and is less liable to be rendered inoperative by wear incident to its use. Furthermore, by the peculiar arrangement of parts, namely, the straight shank carrying an integral jaw, a sliding stem carrying an integraljaw and an integral tooth toengage teeth or notches upon the adjacent face of the shank, the simple reversed, or oppositely disposed loop-shaped links, and the operating lever which is fulcrumed between the arms of one of said links, I am enabled to avoid the use of complicated castings, and provide a wrenchin which all of` the parts are exposed to view whereby they may be readily repaired, cleaned, replaced, dac.

Having thus described my invention, what I claim,and desire to secure byLettersPatent of the United States, is`

In a wrench, the combination of the 'shank provided with a series of teeth and having a xed jaw provided with a coneaved serrated engaging face, a sliding jaw provided with a stem terminating at its lowei` end in a tooth engaging the shank, the upper loop-shaped guiding link embracing the shank and fitting snugly thereon and pivoted t-o the sliding jaw, the lower guiding link embracing the shank and the stem, and a cam lever pivotally mounted in the lower link, substantially xo as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ELI II. GOSLIN.
